Am Folowing dieses tutorial Qt 4.8 mit Visual Studio 2013 zu kompilieren, aber Nmake i nach dem Laufen bekommen:

Vielen Dank für jede Hilfe

Answer 1

Zur Fixierung 'rund' und 'roundf' Fehler ersetzen (Linien 103 und 110):

static double round(double num) 
static float roundf(float num) 

mit:

static inline double round(double num) 
static inline float roundf(float num) 

zu beheben 'Vorzeichenbit' Fehler sie umschließen mit Makro folgenden (Linie 128):

#if _MSC_VER < 1800 
inline bool signbit(double num) { return _copysign(1.0, num) < 0; } 
#endif 

Answer 2

Sie „vcvars32 gelaufen .bat "vor dem Kompilieren? Es scheint, die Umgebungsvariablen von VC++ sind nicht ordnungsgemäß festgelegt.

Informationen zur Umgebung von VC++ finden Sie unter http://msdn.microsoft.com/en-us/library/f2ccy3wt.aspx.

Answer 3

Ihr Problem ist, dass Sie nicht Visual Studio 2012, aber 2013 VS 2012 verwenden Sie ist VS11 während VS 2013 VS12 und Ihrem Pfad "C: \ Program Files (x86) \ Microsoft Visual Studio 12.0" ist gehört zu VS 2013.

Das Kernproblem ist jedoch, dass VS 2013 ist C99-konform, die Probleme in der V8-Engine und Javascriptcore verursacht.

Momentan gibt es keine Lösung, sondern manuelles Patchen.

Answer 4

die offizielle patch für VS 2013-Kompatibilität verwenden.

Answer 5

Die beiden oben vorgeschlagenen Patches waren nicht genug. In meinem Fall, nachdem sie zu Qt 4.8.5 Anwendung habe ich einen anderen Fehler:

Answer 6

@ AppDealer's awnser funktioniert, wenn Sie es auf beide Instanzen der MathExtras.h Datei anwenden müssen. (Ein in JavaScriptCore und ein anderer in Webkit Nach , die Sie in einem HashSet Build Problem laufen.

No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called .\wtf/HashSet.h 

Beide Probleme werden Korrekturen mit dem patch, die auf this issue gefunden werden kann.
